摘要： PURPOSE:To obtain an inexpensive vacuum cleaner whose running property is satisfactory and which does not damage the floor surface by providing a suction nozzle for executing a suction by approaching the floor surface by suction force of an electric air blower, and a blowing nozzle for blowing an exhaust of the electric air blower to the floor surface, and constituting a circulating air course of the suction nozzle, the electric air blower and the blowing nozzle. CONSTITUTION:When a mode switch (for instances a 'strong' mode switch) of an operating switch part 18 is depressed, input power corresponding to a 'strong' mode is supplied to an electric air blower 15, and also, an LED corresponding to the 'strong' mode is turned on, and the electric air blower 15 executes a suction by the maximum suction force. Also, by suction force of the electric air blower 15, dust on the floor surface is sucked together with an air flow from a suction nozzle 27, and this dust passes through a suction tube 28 and a suction passage 22 together with the air flow and is collected into a paper pack 16. Thereafter, an exhaust of the electric air blower 15 passes through an exhaust passage 20 and a blowing tube 29 and is blown to the floor surface from a blowing nozzle 26, and allows the dust on the floor surface to soar so as to be sucked easily. In such a way, dust which intrudes into a clearance of a carpet, etc., is also allowed to soar so as to be sucked easily.

摘要： PROBLEM TO BE SOLVED: To perform a uniform heating of an item to be heated and reduce an irregular heating as well as an irregular freezing by a method wherein a flat reflecting plate is arranged at a wall surface of a heating chamber in such a way that it is being oppositely faced against a central lower part of the heating chamber with an angle with the bottom surface of the heating chamber being more than 45 deg. and then a high-frequency wave is reflected from an electricity supplying port to the central lower part of the heating chamber. SOLUTION: A high-frequency wave 30 fed from a magnetron 3 passes through an electricity supplying port 4 and is fed into a heating chamber 1. A component of the high-frequency wave 30 fed out into the heating chamber 1 frequently advances in straight forward, so that almost of the component of the high-frequency wave 30 is incident to a flat reflecting plate 51 in the heating chamber 1, reflected by the flat reflecting plate 51 in a slant downward direction so as to radiate against a region near the center of the item to be heated 6 on a table 5. In this case, an inclination of the flat reflecting plate 51 against the bottom surface of the heating chamber 1 is set to be 45 deg. or more and almost the high-frequency wave 30 fed out of the electricity supplying port 4 into the heating chamber 1 can be radiated by the flat reflecting plate 52 through once reflection against the region near the central part of the item to be heated on the table 5, resulting in that a heating efficiency is improved.
